High Speed Wireless Internet Service

What is a high speed wireless internet service?

Creating the definition of high speed wireless internet service

Service data access or high speed wireless internet service more and more prevalent today, almost all mobile operators in Indonesia have been providing this service. This is made possible by the rapid development of wireless technology on the mobile phone network. There are two types of mobile networks operating in Indonesia, namely the GSM-based mobile network (cellular Global Mobile) and another one based on CDMA (coded Division Multiple Access). Each GSM and CDMA cellular operators are equally experienced in the technology development effort to improve the quality of data and voice communication speed. This is also triggered by the rapid technological embedded on the handset / mobile phone in the market, and currently runs HSDPA technology was born in GSM and EVDO CDMA network running in.

HSDPA
HSDPA (High-Speed Downlink Packet Access) is born from the development of WCDMA technology, is a protocol or a mobile phone which is also referred to as 3.5 G technology Starting from a network of Universal Mobile Telecommunications System (UMTS) which is known as 2.5 G, HSDPA increase the evolutionary paths of data to use larger capacity up to 14 Mbps. In the first phase of HSDPA technology in Indonesia introduced at speeds up to 3.6 Mbps, then followed by a second phase which experienced the development of 7.1 Mbps.

Evolution of WCDMA was developed to increase data transfer speeds to be 5x higher by defining a new WCDMA channel is a high-speed downlink shared channel (HS-DSCH). Until now, this HSDPA technology used only in the direction of communication down to the cell phone / HSPDA phone has several features to reduce delays in the downloading of the data (the delay) and gives instant feedback when the user performs high speed wireless internet service, while also increasing system capacity without requiring additional frequency spectrum and will reduce the cost of mobile data services significantly.
Use HSDPA particular environment can make downloading files from the Internet to reach 3.6 Mbps, also in the running video streaming users can enjoy up to 300 Kbps speeds. Unfortunately, if there is a decrease signals a network. The HSDPA technology is not good even with the bias current will decrease to 2.5 G to 3G lines could even be to the GPRS network. Of course this happens the inconvenience factor for the users who are not in line 3.5 G.

EVDO
EVDO stands for Evolution Data Optimized or Evolution Data Only, is a standard in high-speed wireless broadband. Official terms issued by Telecommunications Industry Association is CDMA2000, also known as EV-DO and 1xEV-DO 1xEvDO. EVDO one of two main kinds of wireless standard 3rd generation or 3G, as for other standards are WCDMA, a high-speed data interfaces through the air. Walking in the network MVA, which uses mathematical methods to be able to skip the use of wireless devices to send data concurrently on the same frequencies.

The presence of 3G cellular networks aim at improving the speed data and voice, but still has a problem in applying high speed wireless internet service network with minimal bandwidth or frequency range that is used today.

EVDO technology created by the development of Qualcomm’s technology has been developed, which streamline / reduce the number of radio frequencies on the FM waves, so that not a lot of data that utilize the bandwidth. EVDO wireless network instead of utilizing the first barrier between the sender and recipient, by adopting the same approach to the internet which splits the data in small pieces called high speed wireless internet service packets.

Shipping the packages shipped independently of other packets, this can save bandwidth usage that allows use by wireless devices. When the telephone conversation did not occur there must also pass the package because there are no packets sent. Alternatively, when an Internet site is accessed, there will be no bandwidth, which was used until the site began to send web pages. In theory, that exceeded the speed can reach 2.4 Mbps EVDO up to 3-6 Mbps. Of course, much faster if compared with high speed wireless internet service and cable broadband available.

Advantages of CDMA EVDO than usual, certainly more save frequency spectrum from the regulator who is very expensive indeed, lower the cost of developing and utilizing the new network. EVDO usage is widely used in the United States and Korea, in Indonesia, currently only a few operators who have adopted this technology. It is not very influential EVDO usage for Asia and several countries in Europe. In a conversation video taken by one in America with the drive at speeds of 60 miles per hour (90 km / h), does not degrade the quality of voice and video are accepted. Unlike HSDPA, if there is a decrease the signals quality, the EVDO is still running smoothly and still providing high speed wireless internet service.
